What causes itchy eyes allergies
The most common allergen is pollen, a powder released by trees, grasses and weeds that fertilize the seeds of neighboring plants. As plants rely on the wind to do the work for them, the pollination season sees billions of microscopic particles fill the air, and some of them finish up in people’s noses and mouths.
Spring bloomers include ash, birch, cedar, elm and maple trees, plus numerous species of grass. Weeds pollinate in the tardy summer and drop, with ragweed being the most volatile.
The pollen that sits on brightly colored flowers is rarely responsible for hay fever because it is heavier and falls to the ground rather than becoming airborne.
Bees and other insects carry flower pollen from one flower to the next without ever bothering human noses.
Mold allergies are diverse. Mold is a spore that grows on rotting logs, dead leaves and grasses. While dry-weather mold species exist, numerous types of mold thrive in moist, rainy conditions, and release their spores overnight. During both the spring and drop allergy seasons, pollen is released mainly in the morning hours and travels best on dry, warm and breezy days.
Tests & diagnosis
A physician will consider patient history and act out a thorough physical examination if a person reports having hay-fever-like symptoms.
If necessary, the physician will do an allergy test.
According to the Mayo Clinic, people can get a skin-prick test, in which doctors prick the skin on a person’s arm or upper back with diverse substances to see if any cause an allergic reaction, such as a raised bump called a hive. [7 Strange Signs You’re Having an Allergic Reaction]
Blood tests for allergies are also available. This test rates the immune system’s response to a specific allergen by measuring the quantity of allergy-causing antibodies in the bloodstream, according to the Mayo Clinic.
The symptoms of allergic rhinitis may at first feel love those of a freezing.
But unlike a freezing that may incubate before causing discomfort, symptoms of allergies generally appear almost as soon as a person encounters an allergen, such as pollen or mold.
Symptoms include itchy eyes, ears, nose or throat, sneezing, irritability, nasal congestion and hoarseness. People may also experience cough, postnasal drip, sinus pressure or headaches, decreased sense of smell, snoring, sleep apnea, fatigue and asthma, Josephson said.

Many of these symptoms are the immune system’s overreaction as it attempts to protect the vital and sensitive respiratory system from exterior invaders.
The antibodies produced by the body hold the foreign invaders out, but also cause the symptoms characteristic of allergic responses.
People can develop hay fever at any age, but most people are diagnosed with the disorder in childhood or early adulthood, according to the Mayo Clinic. Symptoms typically become less severe as people age.
Often, children may first experience food allergies and eczema, or itchy skin, before developing hay fever, Josephson said. «This then worsens over the years, and patients then develop allergies to indoor allergens love dust and animals, or seasonal rhinitis, love ragweed, grass pollen, molds and tree pollen.»
Hay fever can also lead to other medical conditions.
People who are allergic to weeds are more likely to get other allergies and develop asthma as they age, Josephson said.
But those who get immunotherapy, such as allergy shots that assist people’s bodies get used to allergens, are less likely to develop asthma, he said.
Eye allergy relief
To get relief from your eye allergies and itchy, watery eyes, you can take a few approaches:
Part of the body's natural allergic response is the release of histamine, a substance that dilates blood vessels and making the walls of blood vessels abnormally permeable.
Symptoms caused by histamine include a runny nose and itchy, watery eyes.
Antihistamines reduce allergic reactions by blocking the attachment of histamine to cells in the body that produce an allergic response.
Ask about prescription medications
If your allergy symptoms are relatively severe or over-the-counter eye drops are ineffective at providing relief, you may need your eye doctor to prescribe a stronger medication.
Prescription eye drops and oral medications used to relieve eye allergies include:
Remove your contacts
Because the surface of contact lenses can attract and accumulate airborne allergens, consider wearing glasses instead of contacts during allergy season.
Or consider switching to daily disposable contacts that you discard after a single use to avoid the buildup of allergens and other debris on your lenses.
Often, the best choice if allergies are bothering your eyes is to discontinue wearing contacts altogether — at least until every your allergy symptoms are gone.
Also, wearing eyeglasses with photochromic lenses can reduce allergy-related sensitivity to light and can assist shield your eyes from airborne allergens.
The best approach to controlling your eye allergy symptoms is to do everything you can to limit your exposure to common allergens that you know you are sensitive to.
For example, on days when the pollen count is high, stay indoors as much as possible, with the air conditioner running to filter the air.
Use high quality furnace filters that can trap common allergens and replace the filters frequently.
When you do go outdoors during allergy season, wear wraparound sunglasses to assist shield your eyes from pollen, ragweed, etc., and drive with your windows closed.
Use eye drops
Because eye allergies are so common, there are numerous brands of non-prescription eye drops available that are formulated to relieve itchiness, redness and watery eyes caused by allergies.
If your eye allergy symptoms are relatively mild, non-prescription eye drops for allergy relief may work extremely well for you and may be less expensive than prescription eye drops or other medication.
Enquire your eye doctor to recommend a brand to try.
Itchy eyes, a congested nose, sneezing, wheezing and hives: these are symptoms of an allergic reaction caused when plants release pollen into the air, generally in the spring or drop. Numerous people use hay fever as a colloquial term for these seasonal allergies and the inflammation of the nose and airways.
But hay fever is a misnomer, said Dr. Jordan Josephson, an ear, nose and throat doctor and sinus specialist at Lenox Hill Hospital in New York City.
«It is not an allergy to hay,» Josephson, author of the book «Sinus Relief Now» (Perigee Trade, 2006), told Live Science.
«Rather, it is an allergy to weeds that pollinate.»
Doctors and researchers prefer the phrase allergic rhinitis to describe the condition. More than 50 million people experience some type of allergy each year, according to the Asthma and Allergy Foundation of America. In 2017, 8.1% of adults and 7.7% of children reported own allergic rhinitis symptoms, according to the Centers for Disease Control and Prevention (CDC). Worldwide, between 10 and 30% of people are affected by allergic rhinitis, Josephson said.
In 2019, spring arrived early in some parts of the country and later in others, according to the National Phenology Network (NPN).
Spring brings blooming plants and, for some, lots of sneezing, itchy, watery eyes and runny noses. According to NPN data, spring reared its head about two weeks early in areas of California, Nevada and numerous of the Southern and Southeastern states. Much of California, for example, is preparing for a brutal allergy season due to the large quantity of winter rain. On the other hand, spring ranged from about one to two weeks tardy in the Northwest, the Midwest and the Mid-Atlantic U.S. [Watch a Massive ‘Pollen Cloud’ Explode from Late-Blooming Tree]
How do scientists know how much pollen is in the air?
They set a trap. The trap — generally a glass plate or rod coated with adhesive — is analyzed every few hours, and the number of particles collected is then averaged to reflect the particles that would pass through the area in any 24-hour period.
That measurement is converted to pollen per cubic meter. Mold counts work much the same way.
A pollen count is an imprecise measurement, scientists confess, and an arduous one — at the analysis stage, pollen grains are counted one by one under a microscope. It is also highly time-consuming to discern between types of pollen, so they are generally bundled into one variable. Given the imprecise nature of the measurement, entire daily pollen counts are often reported simply as low, moderate or high.
The American Academy of Allergy, Asthma & Immunology provides up-to-date pollen counts for U.S.
What causes eye allergies
Common allergens include pollen, animal dander and mold.
Eye allergies also can be caused by reactions to certain cosmetics or eye drops, including artificial tears used for treating dry eyes that contain preservatives.
Food allergies and allergic reactions to bee stings or other insect bites typically do not affect the eyes as severely as airborne allergens do.
